The ENERGY STAR® Web site states, “Solid-State Lighting (SSL) is the future of lighting, and thanks in part to ENERGY STAR, it'll be here faster than you think. The ENERGY STAR label on SSL luminaires will provide consumers with the confidence that these products meet efficiency and performance criteria established by DOE in collaboration with industry stakeholders.

With test procedures being finalized, the ENERGY STAR SSL program is on schedule to launch September 30, 2008. ENERGY STAR is focusing on lighting applications and products for which the technology has advanced to a point where performance is equal to or better than traditional efficient lighting technologies based on light output, luminaire efficacy and cost. The focus on quality will go a long way to ensure that consumers have a good experience with this new technology.”
